Yan Xing's strategy was to build a small embankment in the upper reaches of the weak water to cut off the weak water and store it. When the weak water is about to overflow the dam, it indicates that the weak water has accumulated enough water. Yan Xing ordered the sergeants to dig the embankment and open the sluice gate to release water. The accumulated flood water rushed towards the small Huishui Castle, and although it was not enough to directly break down the walls of the castle, as long as the water overflowed a certain height, it slowly seeped into the walls and soaked the soil of the walls. The city wall is made of rammed earth, and water can quickly erode the city wall, soaking the soil soft and crispy. It didn't take long for the walls to collapse due to water at the roots. As a result, weak water poured into Huishui City, soaking the defenders in the water, making it difficult for them to move in the water.

At this time, Yan Xing took out the sheepskin raft that had been prepared. The sheepskin raft has a long history, and it is recorded in the "Water Scripture Note", which is also called "leather boat". For the first time, the sheepskin raft should choose the skin of the ram, because the ewe has teats, and the tucks will seep and leak there; secondly, it requires superb slaughtering and peeling skills, if the knife is not accurate, a sheepskin will be wasted; Then it is slowly baked over a fire; Then apply the sheepskin with salt, oil, and water; Finally, tie it up with ashbrush branches, and you're done. Sheepskin rafts have long been popular on the Yellow River, so the Xiliang soldiers made them quickly.

Yan Xing led 5,000 soldiers to row a sheepskin raft and attack through the gap in the city wall with the help of water power. When Sergeant Xiliang rowed the sheepskin raft quickly and comfortably, passing by the Han Suijun soldier who was soaked in water and couldn't move, he could calmly bring him a long spear.

The 5,000 sergeants shouted their trumpets in unison, like dragon boats, and rowed effortlessly towards the fifty-pace-long gap in the city wall. The shouts of the defenders came from the city wall, and Yan Xing ordered the sergeant to raise his bow and shoot. Sergeant Xiliang's riding and archery skills are outstanding, not to mention flat shooting. The arrows flew up the city walls, and immediately a dozen defenders fell into the water below the city, causing a large splash.

With this shot, the city walls basically died down. Because there were not many guards on the city walls, many more were still soaking in the city. Yan marched immediately over the city wall without hindrance and entered the city of Huishui.

Jiang Jian also came to his senses and shouted loudly: "The enemy army has entered the city, where are the crossbowmen?" Shoot your arrows and shoot the enemy's leather boats! ”

Seven crossbowmen rode horses, close to the city wall, and immediately approached Jiang Jian when they heard the words. Jiang Jian saw that there were only seven crossbowmen, so he was in a hurry, and when he looked back, the rest of the soldiers in the Ze Kingdom in the city were wading through the water and struggling to get to him.

Jiang Jian couldn't care about this much, and ordered seven crossbowmen to shoot arrows.

The lone seven arrows flew towards the Xiliang soldiers, and all of them were blocked by the Xiliang soldiers with spears. Jiang Jian saw that it turned out that the crossbowmen had lost their physical strength when they were walking on the water, so they were unable to pull the bow with all their strength, and the arrows they shot had no strength, so the Xiliang soldiers easily shot down with their spears.

The rafts marched quickly, and soon all the five thousand soldiers entered the city. Yan Xing saw that many guards were soaking in the water in the open space near the city gate, and ordered: "Prepare to shoot!" ”

Sergeants Xiliang stopped paddling in their hands, raised their bows and crossbows, and aimed at the guards who were "like in the middle of the water". Jiang Jian couldn't see it well, so he quickly jumped into the water from the horse and lay on his stomach.

"Shoot!" Yan Xing yelled.

"Boom", the arrows roared, and the defenders in the water were immediately shot dead and wounded more than a hundred people. The corpse fell, causing a splash. Blood flowed into the water, staining a large patch of red. The defenders had no desire to fight at all, and fled backwards crying and shouting, removing their heavy armor as they fled.

But still in the water, they can't run fast. The sheepskin rafts approached, and as soon as the Xiliang sergeant on the raft got close to the defenders, he stabbed him and shot him, and the battle became the pursuit of the enemy soldiers by the Xiliang soldiers. The defenders also resisted, but because they were soaked in water, the defenders were too scattered to line up. And there were four or five Xiliang sergeants on a sheepskin raft, and in the face of a guard, they stretched out four or five sharp spears, so that the defenders could not resist at all, and could only be slaughtered by Xiliang sergeant on the ground.

The city was very lively, and the panicked guards cried for their fathers and mothers, and urgently waded through the water to escape, splashing everywhere, as if they were playing in the water. Some of the guards had too much desire to survive, and when they saw that they were running too slowly in the water, they swam directly in the water. Swimming was indeed faster than wading through the water, and all the defenders began to swim in the water. If Ma Chao was there, he would definitely think that this was the scene of the first freestyle competition in the history of Huishui City.

And the Xiliang soldiers who were chasing the defenders of Huishui City were shouting neatly and rowing hard, like the dragon boat race in later generations.

Yan Xing saw that the guards were all swimming in the water, exposing their defenseless backs, so he ordered: "Listen to orders!" Throw spears at enemy soldiers and stab them to death! ”

The Xiliang soldiers raised their spears one after another, aimed at the enemy soldiers who were fluttering in the water, and threw their spears, making a loud sound of "Su Su Su", which was very similar to the javelin competition in later generations.

Dozens of guards were stabbed by spears and floated on the water, blood flowing from the wounds, staining a large area of water red.

Seeing that the situation was not good, Jiang Jian kept lying dormant next to the corpse of the war horse, pretending to be a corpse.

Who knew that the lieutenant general of the Xiliang Army who came to break the city was Yan Xing, the former general of the Han Sui Army. Yan Xing recognized Jiang Yin, and when the sheepskin raft approached, Yan Xing grabbed Jiang Yin's clothes with one hand and slipped him out of the water.

Looking at Jiang Yin's face, which was white from blisters or frightened, Yan Xing smiled and said, "Jiang Yin, you're still hiding!" ”

"Yan Xing, it's actually you, who broke through Wuzhihui Water City!" Jiang Jian said through gritted teeth.

Yan Xing said with a smile: "As the guard of Huishui City, you are very good at water!" ”

Jiang Jian was so angry that he couldn't speak.

Yan Xing handed Jiang Jian over to the sergeant and tied him up, shouting: "Jiang Jian is captured, and those who surrender will not be killed!" ”

Hearing this, the Xiliang soldiers reluctantly stopped the bidding gun competition. Instead of feeling humiliated, the defenders felt relieved and stopped their freestyle, stood up and raised their hands in surrender.

By this time, the blood had already stained a large area red, and almost everyone was soaked in the water. In the vast territory of Zeguo, there were more than 300 corpses floating around, some of which had spears stuck in them.

Yan Xing counted slightly, and there were more than 1,700 troops surrendered. Because of the water, no one could escape, and the guards of Huishui City were rounded.

After the water slowly subsided, Ma Chao led Jia Xu, Zhang Xiu and the main force into Huishui City. Yan Xing escorted Jiang Jian to Ma Chao's horse, pressed him to kneel, and said: "Young master, in this battle, three hundred beheaded, 1,700 enemies were captured, and the guard Jiang Jian was captured alive. Only a dozen of our soldiers were killed, and dozens more were slightly wounded. ”

Ma Chao was very satisfied and said: "Okay, you fought beautifully in this battle, and you will be given a great deal of credit after recovering Hexi." ”
